PR'OTECTlNG-ARMOR FOR PNEUMATIC TIRES.

SPECIFICATION forming part of Letters Patent No. 601,327, dated March 29, 1898.

Application filed September 8 1 97- T 1Nm-6 50,888. (No model.)

To all whom it may concern:

Be it known that 1, ROBERT H. STEVENSON, a citizen of theUnited States, residing at J oliet, in the county of Will and State of Illinois, have invented certain new and useful Improvements in Protecting-Armor for Pneumatic Tires; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had tothe accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to armor for pneumatic tires; and its object is to provide an antipuncture-band adapted to effectually protect the pneumatic tube of a tire from punctures without detracting from the resiliency of the tire.

The characteristic features of my improved armor will be fully described hereinafter and are illustrated in the accompanying drawings, in which- Figure 1 is a perspective view showing a section or segment of the band. Fig. 2 is a central longitudinal section on the line 2 2 of Fig. 1. Fig. 3 is a perspective view of one of the inner connecting plates or members of the band detached and provided with wires for securing thereto the edges of the outer plate, and Fig. 4 is an enlarged detail view illustrating the manner of hingingthe edges of the outer plates to the wires of the inner plates.

A series of metallic plates 1, preferably of aluminium and bent to semicircular form to conform to the outer face'of the pneumatic tube of the tire, are fitted together edge to edge and hinged to inner plates 2 by means of wires 3 and 4, which pass through or are sewed or otherwise secured to the projecting edges 5 of a fabric covering 6, which is applied to each of the hinged plates.

The inner plates 2 are arranged to break joints with the outer plates and are of less width than said outer plates to facilitate an inward yielding of the latter on their hingesupports.

While I do not, of course, restrict my invention to the use of aluminium as the material from which the plates'are made, I have found that particular metal specially adapted for the purpose, owing to its lightness and durability.

The covering 6 of the plates may be of any suitable stout fabric-such as canvas, linen, or the like'and I prefer to cement the same to both faces of the outer plates, leaving a projecting edge 5 at each side of the plate, which is turned or looped around the adjacent wire 3 or 4: and secured thereon, the ends 7 of the wire being passed through openings in the inner plates and bent over or clenched, as shown.

The covering 6 of the inner plates 2 is applied after the Wires 3 or 4 have been clenched thereon, and said covering is glued or cemented to the inner face of the-plate, with its edge 8 overlapping the edges of the plate and se cured by glue or cement to the outer face of the plate.

It will be apparent from the drawings and the foregoing description that each of the outer plates 1 is independently hinged at its opposite edges, thus permitting said plate to yield readily, while the inner plates 2 are se cured at their centers only, their parallel edges being entirely disconnected from the outer plates.

While the specific means shown and described for hinging the edges of the outer plates have been found efficient and inexpensive, it is obvious that other means for bringing the outer and inner plates together might be resorted to without departing from my invention. I therefore desire to include all such modifications in the details of the device as may fall within the scope of the following claims.

It will be understand that the band is to be a continuous or endless band entirely surrounding the annular pneumatic tube of the tire andadapted to be covered by the ordi-' nary outer elastic covering. of the tire.

I claim as my invention- 1. An armor or antipuncture-band for pneu= the plates of one series overlapping those of the other series tobreak joints therewith, and fastening devices for loosely securing the ends of the plates of one series to the surface of the plates of the other series.

3. An armor or antipuncture-band for pneumatic tires, comprising a series of aluminium plates each provided with a covering of fabric, in combination with a second series of plates centrally hinged to the transverse meeting ends of the first-named series of plates,

substantially as shown and described.

4. An armor or antipuncture-band forpne umatic tires, comprising an outer and an inner series of metallic plates, the edges of the outer series being loosely secured to the outer 5" face of the inner ,plate, each of said plates having a coating or covering of fabric.

5. Thecombination with the outer fabriccovered plates, of a series of inner plates,

and securing-wires, said inner plates breaking joints with the outer plates, and said securing-wires engaging the edges of the fabric covering of the outer plates and having their ends passed through and clenched upon, the inner plates.

6. The combination with the outer fabric- ?covered plates, fitting together edge to edge, of inner plates overlapping the joints between the outer plates, securing-wires engaging the projecting edges of the fabric covering of the outer plates and having their ends extending through openings in the inner plates, and clenched thereon, and strips of fabric applied to the'inner faces of'the inner plates to cover jthe clenched ends of the wires.

In testimony whereof I affix my signature tin presence of two witnesses. g; ROBERT H. STEVENSON. i2 Witnesses:
